GLYOXYLIC ACID

Safety grade: A

Glyoxylic acid is a mild chemical compound used in hair care products that works similarly to formaldehyde but is considered gentler. It helps relax or straighten hair by breaking down and reforming the hair's protein structure.

This ingredient is used in hair straightening and waving treatments to alter hair texture, while also helping to balance pH levels in formulations and reduce static electricity in hair.
